RESUMEN
Toll - like receptors represents the first line of defense against foreign pathogens and play an essen-tial role in the innate immune response. Toll - like receptor 9(TLR9)is a major receptor mediating CpG DNA signal transduction,which can not only resist inflammation but also induce inflammatory damage. Studies show that the activa-tion of TLR9 which mediated by endogenous nucleic acid released during viral myocarditis (VMC)can cause the heart damage and be involved in the process of VMC. Further study on the role of TLR9 signal in VMC will provide a theoreti-cal foundation for further revealing the pathogenesis of VMC and seeking effective treatment.

RESUMEN
Objective To explore the expression of tankyrase (TNKS) and its relationship with WNT/β-catenin signal?ing pathway in lung acinar adenocarcinoma. Methods Seventy-two samples of single subtype alveolar like lung adenocarci?noma (lung adenocarcinoma group) and 67 specimens of normal lung tissue adjacent to carcinoma (adjacent to carcinoma group) were collected. Immunohistochemical method was used to detect expressions of TNKS, beta-catenin (β-catenin) and c-myc protein. The correlation of each protein expression in lung adenocarcinoma tissues was analyzed. The differential ex?pression of TNKS was detected by Western blot assay in two groups. Results Tankyrase protein was mainly expressed in cy?toplasm. The expression ofβ-catenin protein was mainly in cytoplasm and nuclear of lung adenocarcinoma. The expression ofβ-catenin was mainly in cytoplasm, and a small amount was in nuclear of the adjacent group. The c-myc protein was ex?pressed mainly in the nucleus. The positive expression rates of TNKS,β-catenin and c-myc protein were significantly high?er in lung adenocarcinoma group than those of adjacent to carcinoma group (P<0.05). The expression ofβ-catenin in cyto?plasm and nucleus was positively correlated with the expression of TNKS and c-myc (P<0.05). Western blot analysis showed that the relative expression level of TNKS was significantly higher in lung adenocarcinoma group than that of adja?cent to carcinoma group (0.497 ± 0.021 vs. 0.237 ± 0.015, t=13.00, P<0.01). Conclusion Abnormally high expression of TNKS in lung adenocarcinoma may promote the occurrence of lung cancer by regulating the WNT signaling pathways. Inhib?iting TNKS expression may become a new target to treat lung adenocarcinoma.

The clinical data of 76 children with EFE admitted from June, 1998 to December, 2009 was retrospectively analyzed. Tachypnea、 cough and cyanosis were common and all presented with heart failure. Electrocardiogram revealed sinus tachycardia 、left ventricular hyperthrophy and ST-T alterations. On chest radiograph 54 cases (54/76) had a cardiothoracic ratio ＞ 0. 65 and 33 with pneumonia.Echocardiopraphy revealed lowered left ventricular systolic function in all cases and decreased left ventricular diastolic function in 21 (21/76). 63 cases (63/76) presented with thickened and enhanced left ventricular endocardium and 11 (11/76) with thickened interventricular septals. All were treated with digitalis. 58children were improved and discharged, 10 gave up therapy and 8 died during hospitalization. 41 out of 58 improved cases were followed for 1 - 4 years, with 2. 6 years on average. Among them 28 were clinically cured, 7 deteriorated and 6 died of heart failure. Echocardiography is of diagnostic value for ERE. Systolic and diastolic function of the heart can be used to predict the outcome. Pulmonary infection is a major risk factor associated with deterioration. Long-term treatment is imperative to improve the prognosis.
RESUMEN
A novel silica monolithic stationary phase functionalized with butylaminopropyl ligands for capillary electrochromatography(CEC) has been presented. The monolithic capillary columns were prepared by a sol-gel) process and subsequent a chemical modification. The amino groups on the surface of the stationary phase are meant to generate a substantial anodic electroosmotic flow (EOF). The butyl and propyl groups provide) hydrophobic properties. To evaluate the column performance, effects of buffer pH and organic modifier content on the EOF and electrochromatographic retention behavior of alkylbenzenes, organic acids and anilines were investigated. The monolithic stationary phase exhibited reversed phase (RP) chromatographic behavior toward neutral solutes. The model organic acid anion solutes were separated by the mixed mode mechanism, which comprised RP interaction, weak anion-exchange, and electrophoresis. Basic compounds such as anilines) were well separated on the butylaminopropyl silica monolithic column without peak tailing.
